NAME

       cfsetospeed - set output baud rate

SYNOPSIS

       #include <termios.h>

       int cfsetospeed(struct termios *termios_p, speed_t speed);

DESCRIPTION

       The cfsetospeed() function shall set the output baud rate stored in the
       structure pointed to by termios_p to speed.

       There shall be no effect on the baud rates set in the hardware until  a
       subsequent  successful  call  to  tcsetattr()  with  the  same  termios
       structure. Similarly, errors resulting from attempts to set baud  rates
       not  supported  by  the  terminal device need not be detected until the
       tcsetattr() function is called.

RETURN VALUE

       Upon successful completion, cfsetospeed() shall return 0; otherwise, it
       shall return -1 and errno may be set to indicate the error.

ERRORS

       The cfsetospeed() function may fail if:

       EINVAL The speed value is not a valid baud rate.

       EINVAL The value of speed is outside the range of possible speed values
              as specified in <termios.h>.
